Duet

In my yard a bird sings a simple interval hi to lo,
A to G, to rest a measure: repeat, indefinitely I suppose.
I back her on nylon guitar, soulful picking about A Minor, a little bit R&B.
The bird impromptu adds F#, I respond: arpeggios, G Major 7th plus
touching harmonics harplike percussively as I go – startled,
she flies away glissando.
